Struct BlockingI2c 

pub struct BlockingI2c<I2C: Instance> { /* private fields */ }

embedded-hal compatible blocking I2C implementation

NOTE: Before using blocking I2C, you need to enable the DWT cycle counter using the DWT::enable_cycle_counter method.

Implementations

impl<I2C: Instance> BlockingI2c<I2C>

pub fn new<const R: u8>( i2c: impl Into<Rmp<I2C, R>>, pins: (impl RInto<I2C::Scl, R>, impl RInto<I2C::Sda, R>), mode: impl Into<Mode>, rcc: &mut Rcc, start_timeout_us: u32, start_retries: u8, addr_timeout_us: u32, data_timeout_us: u32, ) -> Self

Creates a blocking I2C1 object on pins PB6 and PB7 or PB8 and PB9 using the embedded-hal BlockingI2c trait.

impl<I2C: Instance> BlockingI2c<I2C>

pub fn write(&mut self, addr: u8, bytes: &[u8]) -> Result<(), Error>

pub fn reset(&mut self)

pub fn read(&mut self, addr: u8, buffer: &mut [u8]) -> Result<(), Error>

pub fn write_read( &mut self, addr: u8, bytes: &[u8], buffer: &mut [u8], ) -> Result<(), Error>

pub fn transaction_slice( &mut self, _addr: u8, _ops_slice: &mut [Operation<'_>], ) -> Result<(), Error>

impl<I2C: Instance> I2c for BlockingI2c<I2C>

fn read(&mut self, addr: u8, buffer: &mut [u8]) -> Result<(), Self::Error>

Reads enough bytes from slave with address to fill read.

fn write(&mut self, addr: u8, bytes: &[u8]) -> Result<(), Self::Error>

Writes bytes to slave with address address.
